Application 1116a November 16,1906. Serial No. 287,653.

To aZZ whom it may concern:

, Be it known that I, ALFRED H. Him PHREY, a citizen of the UnitedStates, resid.

ing-at New York city, in the State of New York, haveinvented certainnew'and-useful.

inverted burners in which all of theburners are accessible and capableof independent adjustment; third, to provide an improved gas-lamp inwhich the burner or burners are properly supplied with air and at thesame. time are fully protected; fourth, to provide an improved gaslamphaving aninvertedburner or burners in which the liability of backlighting is reduced to a minimum; fifth, to provide an improved gas-lampin which "the parts are eifectively protected from excessive heat fromthe burners; sixth, to provide in a gas-lamp having an inverted burneror burners an improved globe and shade support; seventh, to provide in agas lamp an improved pilot-light and means for flashing the same eighth,to provide in a gaslamp an improved valvemechanism; ninth, to provide ina gas-lamp having aninverted burner an improved mantle-support.

Further objects and objects relating to structural details willdefinitelyappear from the detailed description to follow.

I accomplish the objects of myvinvention by the devices and meansdescribed in'the following specification.

The invention is clearly defined, and pointed out in the'claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawings, forming a part of thisspecification, in which-.

A pipe 6 is rovidedfor the other arm of the coupling 0 but this is preferably a blind pipe,so that only one valve, as D, is required to control the'delivery'of thegas, and at the same time the-valve is located close to the burners. v f

The burners being grouped about the chimney areinpositionso that the fresh air'isdraw-n up through the mantles, therebyinsuring perfect combastion of thega'ses.

By arranging the burners in an inverted position there isnothing belowthe burners to obstruct the light or to'cast shadows. By

thus arranging the parts I- secure a lamp the candle-power of which isgreatly in excess of the incandescent lam swhich have"heretofore'corne-t'o-my knowledge.

I have illustrated my Improved gas lamp in detail in the form preferredby me on ac.- count of its structural simplicity and economy andconvenience in operation-and ad'- justment. I am-,however, aware that,it is capable of very great yari'at'ion in structural details wlthoutdepartmgh om my invention.

Having thus described my invention; what I claim as new', and desire-tosecureby' Letters Patent, is-
